Danfoss 060L112166 KP-77 Temperature Control

The Danfoss 060L112166 KP-77 Temperature Control is a heavy-duty industrial thermostat engineered for precise thermal regulation in HVACR systems, steam applications, and industrial boiler controls. Operating within a 68-140°F (20-60°C) temperature range, this unit features a single-pole double-throw (SPDT) snap-action switch, allowing for direct control of single-phase AC motors up to 2 kW or as a pilot device in larger control circuits. Utilizing an adsorption charge within its 2000mm (approx. 80-inch) capillary tube and remote bulb (9.5 x 85 mm), the KP-77 ensures consistent performance even when the housing is colder than the sensor. The adjustable differential of 6.3 to 18°F (3.5 to 10.0 K) provides technicians with the flexibility to fine-tune cycling and prevent short-cycling in critical heating and cooling applications. Rated at IP30, this control is designed for reliable indoor mounting with a standard rubber cable gland for 6-14mm wiring, making it a staple for contractors requiring a robust mechanical temperature switch.

• Versatile SPDT Switching: High contact load capacity (16A AC1/AC3) allows for direct motor control or alarm signaling.
• Fail-Safe Adsorption Charge: Suitable for frost protection and applications where sensor-to-housing temperature gradients vary.
• Precision Tuning: Features a manual adjustable differential to optimize system response times and equipment longevity.
• Robust Construction: Vibration-resistant bellows and ultra-short bounce times minimize contact wear in high-demand environments.
• Standardized Footprint: Compact design and front-facing electrical connections simplify integration into existing control panels.

Is the KP-77 suitable for boiler control?
Yes, its 68-140°F range and adsorption charge make it highly effective for regulating industrial heating and steam systems where high reliability is paramount.

Does this unit require a manual reset?
No, the 060L112166 model is an automatic reset temperature control, ensuring the system resumes operation as soon as the temperature returns within the set differential window.

What is the maximum sensor temperature for this control?
The remote bulb is designed to withstand a maximum sensor temperature of up to 266°F (130°C) without damage to the internal charge or bellows.
